无法在VS17和VS15上还原nuget包
无法在VS17和VS15上还原nuget包
提问于 2018-01-12 16:11:55
这是我第一次使用或.NET框架。
当我第一次尝试构建这个解决方案(https://github.com/QuantConnect/Lean)时--我在他们各自的软件上尝试了解决方案的两个版本(VS17和VS15) --我得到了以下错误(由于相关性原因，本文末尾提到了这些错误)。
从这些错误中，我发现在还原nuget包时会出现问题，但是当我尝试从包含的Nuget控制台安装/重新安装/更新一个包(如QLNet )时，会得到一些错误，例如：
PM> Install package QLNet -Version 1.9.2试图收集与项目“QuantConnect.Lean.Launcher”有关的软件包“QLNet.1.9.2”的依赖信息，目标是“.NETFramework”，Version=v4.5.2‘试图解决软件包'QLNet.1.9.2’与DependencyBehavior‘最低’解析操作的依赖关系，以安装软件包'QLNet.1.9.2‘解析操作来安装从QuantConnect.Lean.Launcher包'QLNet.1.9.2’中成功卸载的'QLNet.1.10.0‘包中删除的包'QLNet.1.10.0’。'C:\Users\Work\QuantConnect\Lean-master\packages‘安装失败。回滚..。包'QLNet.1.9.2‘不存在项目'QuantConnect.Lean.Launcher’包'QLNet.1.10.0‘已经存在于文件夹中，添加包'QLNet.1.10.0’到'packages.config‘安装-软件包:未能添加对'QLNet’的引用。一行:1字符:1+ QLNet -Version 1.9.2 + CategoryInfo : NotSpecified：(:) Install-Package，Exception + FullyQualifiedErrorId : NuGetCmdletUnhandledException，NuGetCmdletUnhandledException
或
PM> Update -reinstall QLNet试图收集与项目“QuantConnect”有关的多个包的依赖关系信息，以“.NETFramework，Version=v4.5.2”为目标收集依赖信息，尝试解决多个包的依赖关系花费了5，32秒。解析依赖信息需要0 ms解析操作安装在'C:\Users\Work\QuantConnect\Lean-master\packages'.中找到的软件包“QLNet 1.9.2”安装失败。回滚..。执行nuget操作采取了3,73秒更新-包:无法找到中央目录记录的结束。一行:1字符:1+更新-包-reinstall QLNet +~~+ CategoryInfo : NotSpecified：(:)更新-包，异常+ FullyQualifiedErrorId : NuGetCmdletUnhandledException，CategoryInfo
我还从这个页面下载并执行了nuget.exe - recommended latest v4.4.1和VS 2015 VSIX - latest v3.6.0：https://www.nuget.org/downloads，但是没有什么改变。
我该怎么办？
(这就是我尝试构建解决方案时得到的结果：

无法在VS17和VS15上还原nuget包
在构建解决方案之前，您应该还原nuget包。
通常，当我们与其他人共享解决方案时，我们将忽略packages文件夹。因此，在下载该解决方案后，您将找到文件夹:C:\Users\Work\QuantConnect\Lean-master\packages丢失了。
您应该右键单击解决方案，选择还原NuGet Packages。恢复完成后，您可以构建解决方案，而不会出现此错误：
您可以检查该文件夹以确认包是否已被还原。
对于您的问题，我建议您可以删除packages文件夹，然后通过选择“还原NuGet包”来恢复包。
顺便说一下，包还原主要是通过Visual中的Tools > Options > NuGet Package Manager启用的：
详细信息请参见包恢复。
